Abstract

Способ получения полых металлических микросфер, включающий образование капель жидкого металла в плазменной дуге и подачу в плазменный поток дополнительного газа для раздувания капель расплава, отличающийся тем, что образование капель осуществляют в плазменной дуге движущегося в канале дугового разряда при протекании газового потока под давлением 5 - 10 кбар с последующим резким падением давления до 1 - 3 кбар, а дополнительный газ вводят в виде газообразных продуктов детонации, образовавшихся при взрыве микрозаряда взрывчатого вещества вне потока в канале.A method of producing hollow metal microspheres, including the formation of liquid metal droplets in a plasma arc and the supply of additional gas to the plasma stream to inflate melt drops, characterized in that the formation of droplets is carried out in the plasma arc of an arc discharge moving in the channel during gas flow under a pressure of 5-10 kbar, followed by a sharp drop in pressure to 1 to 3 kbar, and additional gas is introduced in the form of gaseous detonation products formed during the explosion of an explosive microcharge does not flow in the channel.
